Description
本發明係關於半導體裝置、製造方法以及電子裝置,特定而言係關於可藉以減小製作成本之半導體裝置、製造方法以及電子裝置。The present invention relates to a semiconductor device, a manufacturing method, and an electronic device, and more particularly to a semiconductor device, a manufacturing method, and an electronic device which can reduce manufacturing costs.
以CMOS(互補金屬氧化物半導體)影像感測器為代表之固態成像裝置已開始使用WL-CSP(晶圓級晶片大小封裝)。WL-CSP涉及在自一半導體基板切掉晶片之前形成端子及佈線。Solid-state imaging devices typified by CMOS (Complementary Metal Oxide Semiconductor) image sensors have begun to use WL-CSP (Wafer Level Wafer Size Package). WL-CSP involves forming terminals and wiring before cutting a wafer from a semiconductor substrate.
WL-CSP製造步驟包含一製程,舉例而言,藉由該製程形成自一半導體基板之背部通向該半導體基板內部之金屬墊的一細垂直孔(通孔)。形成垂直孔係極大地影響半導體元件之製作成本之一製程。The WL-CSP fabrication step includes a process by which, for example, a fine vertical via (via) of a metal pad from the back of a semiconductor substrate to the interior of the semiconductor substrate is formed. Forming a vertical hole system greatly affects one of the manufacturing costs of the semiconductor element.
已使用DRIE(深反應性離子蝕刻)作為一前段製程來在一矽晶圓中形成垂直孔。然而,DRIE涉及高裝置成本。此外,DRIE需要一光微影步驟,其中在將一光敏物質施加至一矽晶圓表面之後以圖案形式將其曝光。DRIE (Deep Reactive Ion Etching) has been used as a front-end process to form vertical holes in a wafer. However, DRIE involves high device costs. In addition, DRIE requires a photolithography step in which a photosensitive material is exposed in a pattern after it is applied to a wafer surface.
作為一對策,已提出使用利用一雷射鑽之一基板成形技術來在一矽晶圓中形成一垂直孔之一製程。使用一雷射鑽之製程藉由一雷射光束之輻照在一基板中形成一垂直孔,且不需要一光微影步驟。此外,由於一雷射鑽裝置較便宜,因此雷射鑽製程比DRIE製程在製作成本方面有利得多。As a countermeasure, it has been proposed to use a substrate forming technique using a laser drill to form a vertical hole in a wafer. The process of using a laser drill forms a vertical hole in a substrate by irradiation of a laser beam, and does not require a photolithography step. In addition, because a laser drilling apparatus is relatively inexpensive, the laser drilling process is much more advantageous in terms of manufacturing cost than the DRIE process.
然而,舉例而言,藉助一雷射鑽非常難以以使得在垂直孔到達半導體基板內部之金屬墊時即停止鑽孔之此一準確度來控制該製程。However, by way of example, it is very difficult to control the process with the aid of a laser drill such that the vertical hole reaches the metal pad inside the semiconductor substrate, i.e., the accuracy of stopping the drilling.
就此而言,JP-A-2007-305995揭示一半導體裝置製造方法,藉由該方法將一金屬凸塊安置於一半導體基板內部之金屬墊上,且其中藉助到達該金屬凸塊之一雷射鑽來形成一垂直孔。在此方法中,金屬凸塊用作形成垂直孔之雷射鑽之一停止件。舉例而言,將一15 μm厚之電鍍鎳用作金屬凸塊。In this regard, JP-A-2007-305995 discloses a semiconductor device manufacturing method by which a metal bump is placed on a metal pad inside a semiconductor substrate, and by means of a laser drill reaching one of the metal bumps To form a vertical hole. In this method, the metal bumps serve as a stop for the laser drill that forms the vertical holes. For example, a 15 μm thick electroplated nickel is used as the metal bump.
然而,如前述公開案中所揭示使用一金屬凸塊作為雷射鑽之一停止件需要一低雷射輸出以避免穿透金屬凸塊。因此,垂直孔處理花費一長時間。形成用作金屬凸塊之15 μm厚的電鍍鎳亦花費一長時間。用於在一半導體基板中形成垂直孔之長處理時間增加了製作成本。However, the use of a metal bump as a stop for a laser drill as disclosed in the foregoing publication requires a low laser output to avoid penetration of the metal bump. Therefore, vertical hole processing takes a long time. It takes a long time to form a 15 μm thick electroplated nickel used as a metal bump. The long processing time for forming vertical holes in a semiconductor substrate increases the manufacturing cost.
設想增加金屬凸塊之厚度將避免即使在一高雷射鑽輸出下穿透金屬凸塊。然而,形成一厚金屬凸塊增加了額外時間。It is envisaged that increasing the thickness of the metal bumps will avoid penetrating the metal bumps even at a high laser drill output. However, forming a thick metal bump adds extra time.
因此,需要藉由減小垂直孔處理時間之方式來減小製作成本。Therefore, it is necessary to reduce the manufacturing cost by reducing the vertical hole processing time.
因此,期望提供減小製作成本之方式。Therefore, it is desirable to provide a way to reduce manufacturing costs.

The solder ball 40 is connected to a terminal of a wire from which the signal from the sensor unit 12 is output to the outside.
下文參照圖2至圖5闡述垂直孔佈線單元13之製造步驟。The manufacturing steps of the vertical hole wiring unit 13 will be described below with reference to FIGS. 2 to 5.
首先,在圖2中所表示之第一步驟中,在矽晶圓31之氧化物膜31b中形成金屬墊32。舉例而言,金屬墊32表示連接至感測器單元12之選擇電晶體(未圖解說明)之信號線之一端(BEOL:後段製程)。First, in the first step shown in FIG. 2, a metal pad 32 is formed in the oxide film 31b of the germanium wafer 31. For example, the metal pad 32 represents one end of a signal line (BEOL: Back End Process) that is connected to a selection transistor (not illustrated) of the sensor unit 12.
在第二步驟中,在矽晶圓31之頂部表面側上對應於金屬墊32之氧化物膜31b之一部分中形成一孔隙部分41,從而曝露金屬墊32。如自頂部表面所觀看,孔隙部分41經形成以具有小於金屬墊32之一區域,且氧化物膜31b上覆於金 屬墊32之邊緣上。具體而言,考量到用於形成孔隙部分41之製程限度,將金屬墊32形成一較大尺寸。In the second step, a void portion 41 is formed in a portion of the oxide film 31b corresponding to the metal pad 32 on the top surface side of the tantalum wafer 31, thereby exposing the metal pad 32. The pore portion 41 is formed to have a smaller area than the metal pad 32 as viewed from the top surface, and the oxide film 31b is overlaid on the gold On the edge of the pad 32. Specifically, the metal pad 32 is formed into a larger size in consideration of the process limits for forming the void portion 41.
在第三步驟中,在矽晶圓31與金屬墊32之頂部表面上形成玻璃密封劑33。亦在感測器單元12(圖1)之頂部表面上形成玻璃密封劑33。In the third step, a glass sealant 33 is formed on the top surface of the germanium wafer 31 and the metal pad 32. A glass sealant 33 is also formed on the top surface of the sensor unit 12 (Fig. 1).
在第四步驟中,在玻璃密封劑33中形成孔隙42,從而曝露金屬墊32。如自頂部表面所觀看,孔隙部分42係以大於形成於氧化物膜31b中之孔隙部分41之區域之一尺寸形成於玻璃密封劑33中,以便確保金屬墊32曝露於頂部表面側上。上覆於金屬墊32之邊緣上之氧化物膜31b亦曝露於頂部表面側上。In the fourth step, the pores 42 are formed in the glass sealant 33, thereby exposing the metal pad 32. The pore portion 42 is formed in the glass sealant 33 in a size larger than one of the regions of the void portion 41 formed in the oxide film 31b as viewed from the top surface, in order to ensure that the metal pad 32 is exposed on the top surface side. The oxide film 31b overlying the edge of the metal pad 32 is also exposed on the top surface side.
應注意,在第四步驟中,如圖4中所圖解說明,與在玻璃密封劑33中形成孔隙部分42同時,在形成於感測器單元12之頂部表面上之玻璃密封劑33中形成一孔隙部分43。圖4圖解說明形成於玻璃密封劑33中之孔隙部分42,及經形成用於感測器單元12之孔隙部分43。It should be noted that in the fourth step, as illustrated in FIG. 4, while forming the pore portion 42 in the glass sealant 33, a glass sealant 33 formed on the top surface of the sensor unit 12 is formed. Pore portion 43. FIG. 4 illustrates the aperture portion 42 formed in the glass sealant 33, and the aperture portion 43 formed for the sensor unit 12.
在第五步驟中,在形成於氧化物膜31b中之孔隙部分41中,及在形成於玻璃密封劑33中之孔隙部分42中形成停止件層34。可藉由使用諸如絲網印刷、噴塗及柱形凸塊形成方法來形成停止件層34。In the fifth step, the stopper layer 34 is formed in the pore portion 41 formed in the oxide film 31b, and in the pore portion 42 formed in the glass sealant 33. The stopper layer 34 can be formed by using methods such as screen printing, spray coating, and stud bump formation.
圖5A示意性表示絲網印刷。在絲網印刷中,將作為停止件層34之材料的一導電膏51置於具有對應於形成於玻璃密封劑33中之孔隙部分42之一孔之一絲網52的頂部表面上,且使用一橡皮輥53將其攤鋪於絲網52上。因此,透過該孔 穿過絲網52之膏51填充孔隙部分42且形成停止件層34。Fig. 5A schematically shows screen printing. In screen printing, a conductive paste 51 as a material of the stopper layer 34 is placed on the top surface of the screen 52 having a hole corresponding to one of the aperture portions 42 formed in the glass sealant 33, and one is used. The rubber roller 53 spreads it on the screen 52. Therefore, through the hole The void portion 42 is filled through the paste 51 of the screen 52 and forms a stopper layer 34.
圖5B示意性表示噴塗。在噴塗中,透過一噴嘴54將作為停止件層34之材料的導電膏51噴射至跡線部分中。膏51填充形成於玻璃密封劑33中之孔隙部分42,且形成停止件層34。Fig. 5B schematically shows spraying. In the spraying, the conductive paste 51 as a material of the stopper layer 34 is ejected into the trace portion through a nozzle 54. The paste 51 fills the void portion 42 formed in the glass sealant 33, and forms a stopper layer 34.
停止件層34係以此方式形成,且具有與玻璃密封劑33大約相同之厚度(舉例而言,約50 μm)。The stopper layer 34 is formed in this manner and has approximately the same thickness as the glass sealant 33 (for example, about 50 μm).
在圖3中所圖解說明之接下來第六步驟中,經由玻璃密封劑33將玻璃基板14接合至矽晶圓31之頂部表面。此外,在此步驟中,藉由研磨矽晶圓31之底部表面側(BGR:背部研磨)減小矽晶圓31之厚度。In the next sixth step illustrated in FIG. 3, the glass substrate 14 is bonded to the top surface of the germanium wafer 31 via a glass sealant 33. Further, in this step, the thickness of the tantalum wafer 31 is reduced by grinding the bottom surface side (BGR: back grinding) of the tantalum wafer 31.
在第七步驟中,使用一雷射鑽穿過金屬墊32至停止件層34形成垂直孔35。此處,雷射鑽停止在(舉例而言)比JP-A-2007-305995中所揭示之金屬凸塊厚之停止件層34處,且即使在一高輸出下也不會進一步前進。具體而言,藉由一高輸出雷射鑽在不穿透停止件層34之情形下形成垂直孔35。In a seventh step, a vertical hole 35 is formed through a metal pad 32 to the stop layer 34 using a laser drill. Here, the laser drill is stopped at, for example, the stopper layer 34 which is thicker than the metal bump disclosed in JP-A-2007-305995, and does not advance further even at a high output. In particular, the vertical aperture 35 is formed by a high output laser drill without penetrating the stop layer 34.
在第八步驟中,在垂直孔35及矽晶圓31之底部表面上形成絕緣膜36。In the eighth step, an insulating film 36 is formed on the vertical holes 35 and the bottom surface of the germanium wafer 31.
在第九步驟中,移除垂直孔35之端部表面處之絕緣膜36以將停止件層34曝露於垂直孔35。接著,將金屬晶種層37層壓於停止件層34及絕緣膜36上。因此,停止件層34及金屬晶種層37彼此電連接。隨後形成圖1中所展示之電鍍層38、焊料遮罩39,及焊料球40。In the ninth step, the insulating film 36 at the end surface of the vertical hole 35 is removed to expose the stopper layer 34 to the vertical hole 35. Next, the metal seed layer 37 is laminated on the stopper layer 34 and the insulating film 36. Therefore, the stopper layer 34 and the metal seed layer 37 are electrically connected to each other. A plating layer 38, a solder mask 39, and a solder ball 40 as shown in FIG. 1 are then formed.
此完成了垂直孔佈線單元13。由於停止件層34係藉由將膏51(圖5A及圖5B)裝填至形成於玻璃密封劑33中之孔隙部分42中而形成,因此停止件層34可具有厚約50 μm之一厚度。此外,由於使用了絲網印刷或噴塗,可更快速地形成停止件層34,舉例而言,諸如濺鍍方法中所需處理時間之約1/2至1/10。This completes the vertical hole wiring unit 13. Since the stopper layer 34 is formed by filling the paste 51 (Figs. 5A and 5B) into the void portion 42 formed in the glass sealant 33, the stopper layer 34 may have a thickness of about 50 μm. Further, since screen printing or spraying is used, the stopper layer 34 can be formed more quickly, for example, about 1/2 to 1/10 of the processing time required in the sputtering method.
因此,如在該製造方法之前述製造步驟中增加停止件層34之厚度允許使用比在JP-A-2007-305995中所揭示的製造方法中所使用之雷射鑽高輸出之一雷射鑽。高輸出雷射鑽使得可在一較短之時間段內形成垂直孔35,且因此可自相關技術之垂直孔佈線單元13的製造時間縮短垂直孔佈線單元13的製造時間。此又縮短固態成像裝置11作為一整體之製造時間,且減小固態成像裝置11之製作成本。Therefore, increasing the thickness of the stopper layer 34 as in the aforementioned manufacturing steps of the manufacturing method allows the use of one of the laser drills having a higher output than the laser drill used in the manufacturing method disclosed in JP-A-2007-305995. . The high output laser drill makes it possible to form the vertical holes 35 in a short period of time, and thus the manufacturing time of the vertical hole wiring unit 13 can be shortened by the manufacturing time of the vertical hole wiring unit 13 of the related art. This in turn shortens the manufacturing time of the solid-state imaging device 11 as a whole, and reduces the manufacturing cost of the solid-state imaging device 11.
舉例而言,藉由增加JP-A-2007-305995中所揭示之金屬凸塊之厚度來使雷射鑽停止在金屬凸塊處或許有可能。然而,增加金屬凸塊之厚度不僅花費一長時間來形成金屬凸塊,而且可導致金屬凸塊接觸毗鄰金屬凸塊。相比而言,停止件層34在固態成像裝置11之垂直孔佈線單元13之製造方法中不會發生此一接觸,乃因停止件層34係經形成以便填充形成於玻璃密封劑33中之孔隙部分。For example, it may be possible to stop the laser drill at the metal bump by increasing the thickness of the metal bump disclosed in JP-A-2007-305995. However, increasing the thickness of the metal bumps not only takes a long time to form the metal bumps, but also causes the metal bumps to contact adjacent metal bumps. In contrast, the stopper layer 34 does not occur in the manufacturing method of the vertical hole wiring unit 13 of the solid-state imaging device 11, because the stopper layer 34 is formed so as to be filled in the glass sealant 33. Part of the pores.
此外,由於雷射鑽孔之裝置成本比DRIE之裝置成本便宜,因此就此而言亦可降低固態成像裝置11之製作成本。In addition, since the cost of the laser drilling apparatus is lower than that of the DRIE apparatus, the manufacturing cost of the solid-state imaging apparatus 11 can also be reduced in this respect.
此外,所形成之厚約50 μm之停止件層34可可靠地使垂直孔35之雷射鑽處理停止,且可容易控制雷射鑽製程。此 外,停止件層34之厚度使得雷射鑽製程容易控制,且即使當存在垂直孔35之深度之某種變化時亦可在停止件層34與金屬晶種層37之間獲得一期望之接觸。因此,可認為固態成像裝置11具有針對垂直孔35之深度變化之一穩健設計。Further, the formed stop layer 34 having a thickness of about 50 μm can reliably stop the laser drilling process of the vertical holes 35, and the laser drilling process can be easily controlled. this In addition, the thickness of the stop layer 34 allows the laser drilling process to be easily controlled and achieves a desired contact between the stop layer 34 and the metal seed layer 37 even when there is some variation in the depth of the vertical holes 35. . Therefore, it can be considered that the solid-state imaging device 11 has a robust design for one of the depth variations of the vertical holes 35.
圖6係可用作停止件層34之一材料清單。FIG. 6 is a bill of materials that can be used as one of the stop layers 34.
如上文所闡述,由於垂直孔35係藉由雷射鑽孔形成於矽晶圓31中,因此停止件層34較佳地使用具有比矽(Si)之熔點(1,410℃)高之一熔點之一材料形成,以便使雷射鑽之進展在停止件層34處停止。此外,由於即使使用具有比矽低之一熔點之一材料亦可在垂直孔佈線單元13中將停止件層34製成約50 μm厚,因此雷射鑽可在停止件層34處停止且不會穿透此厚層。As explained above, since the vertical holes 35 are formed in the germanium wafer 31 by laser drilling, the stopper layer 34 is preferably used to have a melting point higher than the melting point (1, 410 ° C) of germanium (Si). A material is formed to stop the progress of the laser drill at the stop layer 34. Further, since the stopper layer 34 can be made to be about 50 μm thick in the vertical hole wiring unit 13 even if one material having a melting point lower than that of the crucible is used, the laser drill can be stopped at the stopper layer 34 and Will penetrate this thick layer.
具有比矽低之熔點之停止件層34材料之實例包含銀(Ag:熔點961℃)、金(Au:熔點1,063℃),及銅(Cu:熔點1,083℃)。Examples of the material of the stopper layer 34 having a melting point lower than enthalpy include silver (Ag: melting point 961 ° C), gold (Au: melting point 1,063 ° C), and copper (Cu: melting point 1,083 ° C).
具有比矽高之熔點之停止件層34材料之實例包含鉻(Cr:熔點1,890℃)、銥(Ir:熔點2,410℃)、鉬(Mo:熔點2,610℃)、鈮(Nb:熔點2,468℃)、鎳(Ni:熔點1,453℃)、鈀(Pd:熔點1,552℃)、鉑(Pt:熔點1,769℃)、釕(Ru:熔點2,250℃)、鉭(Ta:熔點2,998℃)、釩(V:熔點1,890℃)、鎢(W:熔點3,410℃),及鋯(Zr:熔點1,852℃)。Examples of the material of the stopper layer 34 having a higher melting point than yttrium include chromium (Cr: melting point 1,890 ° C), cerium (Ir: melting point 2,410 ° C), molybdenum (Mo: melting point 2, 610 ° C), cerium (Nb: melting point 2, 468 ° C) Nickel (Ni: melting point 1,453 ° C), palladium (Pd: melting point 1,552 ° C), platinum (Pt: melting point 1, 769 ° C), ruthenium (Ru: melting point 2, 250 ° C), ruthenium (Ta: melting point 2,998 ° C), vanadium (V: Melting point 1,890 ° C), tungsten (W: melting point 3,410 ° C), and zirconium (Zr: melting point 1,852 ° C).
舉例而言,易於以一膏形式購得之銀及銅較佳地用作停止件層34。除了上文例示之材料之外,諸如氮化鈦(TiN) 及氮化鉭(TaN)之化合物亦可用作停止件層34。氮化鈦及氮化鉭具有分別為2,930℃及3,090℃之熔點,遠高於矽之熔點,且因此雷射鑽之進展可更可按期望停止於使用氮化鈦或氮化鉭在前述厚度範圍中形成的停止件層34處。For example, silver and copper, which are readily available in a paste form, are preferably used as the stop layer 34. In addition to the materials exemplified above, such as titanium nitride (TiN) A compound of tantalum nitride (TaN) can also be used as the stopper layer 34. Titanium nitride and tantalum nitride have melting points of 2,930 ° C and 3,090 ° C, respectively, which are much higher than the melting point of tantalum, and thus the progress of the laser drill can be stopped as desired using titanium nitride or tantalum nitride at the aforementioned thickness. At the stop layer 34 formed in the range.
應注意形成於垂直孔佈線單元13之前述實例性結構中之金屬墊32之頂部表面上之停止件層34可形成於金屬墊32之底部表面上。It should be noted that the stopper layer 34 formed on the top surface of the metal pad 32 in the foregoing exemplary structure of the vertical hole wiring unit 13 may be formed on the bottom surface of the metal pad 32.
圖7表示包含形成於金屬墊32之底部表面上之一停止件層34'之一矽晶圓31。舉例而言,停止件層34'可藉由在圖2中所闡述之第一步驟中在金屬墊32之前形成停止件層34'來形成於金屬墊32之底部表面上。FIG. 7 shows a wafer 31 comprising a stopper layer 34' formed on the bottom surface of the metal pad 32.
